Need Help with java Inventory program Part3
I need help with this code. I am already a week late on this part because part 2 took to long to code. I am not getting the LeatherBlueDot class to compile. I am getting a message that in my constructor statement saying each variable has private access in class SoftballInv3, but I used the super method to declare them. I am not if I am explaining this correctly. I am very new to Java and struggling. Can anyone help? I am posting three classes needed. The Test class is supposed to display the arrays. Here they are beginning with the Test class.
// Inventory program part two
// for softball inventories
// from Als sporting goods
public class SoftballInvTest3
{
// begins main method
public static void main ( String args[])
{
// creats a welcome message
System.out.println( "Welcome to Al's Sporting Goods softball inventory" );
// displays headers for the inventory
System.out.printf( "\n%4s%26s%10s%5s%9s%11s%13s", "ITEM", "BRAND NAME", "TYPE", "QTY",
"PRICE", "RESTOCK", "INV VALUE" );
// lists all of the arrays used in this program
int itemNumber[] = {1001,1002,1003,1004,1005,1006, 1007};
int ballCount[] = {36, 48, 12, 72, 24, 96, 24 };
double ballPrice[] = { 5.99, 4.99, 5.49, 6.99, 7.99, 1.99, 3.99 };
String itemName[] = {"Blue Dot-Worth", "Gold Dot-Worth", "Green Dot-Worth", "Super Blue Dot-Worth",
"Demarini Evil Ball", "Rawlings practice balls", "Demarini Core 44" };
double subTotal[] = new double [7];
double reStock[] = new double [7];
String coverType[] = {"leather", "synthetic", "synthetic", "leather", "synthetic",
"leather", "leather"};
// created new objects of softballinv2 class
SoftballInv3 softBall1 = new SoftballInv3();
LeatherBlueDot softBall2 = new LeatherBlueDot();
// uses methods of softballinv public class to determine value
softBall1.sortArrayName(itemName);
softBall1.displayArrays(itemNumber, ballCount, ballPrice, itemName, subTotal);
softBall1.getTotalOfInv(subTotal);
softBall2.getReStock(stock);
softBall2.getTotalOfInv(subTotal);
softBall2.sortArrayName( itemName);
softBall2.displayArrays(itemNumber, ballCount, coverType, ballPrice, reStock, itemName, subTotal);

{

} // end method to display the arrays
}I had already tried that once before and didn't work but I went ahead and tried again just to see what error I was getting. There are 5 errors, all say the same thing for each variable from softballinv3 class. The messages are "can't reference variable before super type constructor has been called". I don't understand why it says that because the super type constructor is the first statement in the class.
Here is my code again. Nothing has changed, I am just wrapping the code in tags correctly this time.

}Suggestions:
1. Where your LeatherBlueDot constructor (the one with 6 arguments) calls super, the arguments you have in super don't exist. item, name, balls, prices, and subs are not defined in the LeatherBlueDot class. You probably meant to say super( itemNumber, itemName, ballCount, ballPrice, subTotal );
2. You have the line SoftballInv3 softBall1 = new SoftballInv3(); but you don't have a no argument constructor in your SoftBallInv3 class. You have LeatherBlueDot softBall2 = new LeatherBlueDot(); but you don't have that constructor in the LeatherBlueDot class either.
3. softBall2.getReStock(stock); Where is stock declared?
4. softBall2.displayArrays(itemNumber, ballCount, coverType, ballPrice, reStock, itemName, subTotal); You seem to be calling this wrong (with the wrong number or types of arguments)
